I think that there is no reason to dump your Bitcoins you can just sell them and make your money and then quit with Bitcoin because then you have made some with it. Other wise you will leave empty handed.
If you dump your bitcoins right now you will even make profit but the fact is if you now hold them longer you will make much more profit in the overall experience due to the halving.
Yeah like the Norwegian man who bought few dollars of bitcoin(probably $20-30$, can't remember exactly) and in 2013 it filled his account with around $800,000(probably read this news on theguardian). So the thing is hold as much as you can and you never know one day it might make you a millionaire.
